Asetek Inc., the world’s leading supplier of liquid cooling technology for computers, today announced two new pump technologies that deliver optimized cooling and quieter computing. The new pumps use Liquid Temperature Fan Control technology to automatically adjust fan speeds at the radiator. This technology boosts cooling for significant CPU and GPU overclocking and keeps the computer quiet during less demanding tasks. The Antec KÜHLER H2O 620 liquid CPU cooler is the first product to feature Liquid Temperature Fan Control technology.

Asetek’s new pump technologies give Do-It-Yourself PC hardware and gaming enthusiasts a choice between two liquid temperature fan control strategies:

Interactive liquid temperature fan control for those who like to tweak and monitor their hardware.

Both pump technologies use integrated temperature sensors to monitor liquid temperatures and adjust fan speeds. Preset speed control curves are built into pumps with automatic fan control. Pumps with interactive fan control include a USB interface to Asetek's ChillControl monitoring and control app.

ChillControl gives enthusiasts the ability to define their own speed curves or select between preset curves. It also provides monitoring of liquid temperatures, fan speed, pump speed, and sound level. A purely fun feature of ChillControl is the ability to change the color of the lighting in the pump cap to match your machine color or mood.

“Water has a thermal capacity 4000 times greater than air,” said Steve Branton, Director of Marketing at Asetek. “Liquid Temperature Fan Control technology leverages the higher thermal capacity of Asetek’s liquid coolers to effectively cool CPUs and GPUs across sharp spikes in load without spiking fan speed or noise. The technology gradually ramps fan speed to maintain temperatures during sustained loads delivering an optimized overclocking and quiet computing experience.”

I disagree... (with calling it shit) My H50 with push pull setup is comparable to good aircooling if not better.. Cooling is as good and i can use all of my ram slots. It also doesn't weight as much.. less pressure on my motherboard.

I fully agree, i went from a 1.3kg or near 3lbs full copper scythe ninja to a H50 not just for the temps (that are good with a pair of good fans) but to take the weight off my mobo and to stop me having to blow hot air at my GPU due to the fans not fitting with my RAM on that side.

I tested out an H70 for a few months, and saw it was no better than my previous ifx-14 1:1 fans. Add the factor of the chance that the pump may die out anytime, these things are just not worth it temperature and price wise.

The comments i have seen on multiple boards talking about the pump failing being a risk i say that's nothing special against these types of coolers as that risk comes with every kind of water based cooler yet many people use water cooling quite happily.

I understand it may be seen that these types of cooler have lower quality pumps than ones in custom loops but so far my H50's pump has been running a little over 10,000 hours solid an i would hope that is a sign the pump is of an acceptable quality.... unless it craps out right after i post this

Now all they need is to put a Corsair sticker on them like the h50 and h70 and we have a best-seller.

come on its all asetek, the corsair branded ones are so easy to find but the asetek own brand ones are way harder, if asetek put the effort into marketing and availability that corsair has then asetek branded ones would be best sellers them self

Yes i know you are saying people buy things for the corsair name but i would hope that the majority of people here actually read in to the corsair products they buy such as who makes the product that corsair has either tweaked the spec or simply slapped it's name on.

Id rather have them redirect the budget to equip a more stronger pump and fatter tubes

Go find me a cooler that will cool as good as the h70 and fits a mini itx form factor. These have there place they might have weak pumps they may not be good as the best air coolers but they are smaller and they do let you clear normal sized ram on all boards. Not to mention I stuffed one into a silverstone sg05 easile with no mods something that cannot be done with any cooler with comparable performance.

Cuplex Kryos paired with an Aquaduct 240.... Pricewise another range but definitly better....

From my point of view this things are rubbish....

They didnt perform aswell as some air coolers, yeah they are cheap but no way to cool a graphics card and so on.

If you have an Htpc wich needs this cooling then you did something wrong.... Really wrong....

will this work with my Asetek LCLC 240 Liquid Cooling system w/ 240MM Radiator and Dual Fans

I only see information on using the KÜHLER H2O 620 with it, in the release it says that cooler is the first with "Liquid Temperature Fan Control technology" and i assumed that was needed for it to work so the KÜHLER H2O 620 could possibly be the only thing it works with right now.

At least some features may be compatible with older coolers or all... idk I'm tired

Its best in that scenario in which space is premium yes, but still, Id think it would be better if theyd charge the customer for a stronger pump, and at least 7/16" id, instead of relocating budget for a software and some on board sensor.. and change their rads to copper / brass instead of aluminum while at it.

I think people here mainly make HTPC's that are over powered or as mini gaming machines so need the kind of cooling that is hard to fit in a small space. I want a better CPU cooler for my HTPC but my choices are so limited due to space, a 120mm sealed loop would fit perfectly and beat every other cooler that would fit.

I agree, the true benefit of water cooling is that you can 'move' the hot air 100% out of the case via the radiator.
As Asetek states, the fans on the H50 and the H70 have had problems being controlled by the motherboard temperature sensor (=running max all the time), hence Asetek have developed an internal system that regulates itself: KÜHLER H2O 620 is the first example of this.
